Hi Rodger, Thanks for your answer. Could you please tell me How many Application Server do you have? And what is the customer name?

We've had excellent performance with 4 GB and larger JVMs; our experience with the 1.5 JVM in WAS 6.1 is that you can get excellent performance with large memory allocations. Note, though, that can be dependent on the application. I would be more concerned about the large session sizes - if you're using clustering between guests you'll quite likely see high CPU use serialising sessions that large. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
